A-Share Screen for High Amplitude, Active Volume, and Concentration

Summary

This post proposes an A-share stock screen combining a daily price range of at least one percent with a volume ratio between 1.5 and 6. It also applies two concentration-related filters based on circulating market value and total shares. The rationale is to find stocks with noticeable price movement and active, but not extreme, trading activity.

The post describes the candidates as potentially showing clearer trends and larger price moves, but supplies no backtest, performance data, or evidence that the filters predict returns. It cautions that the screen omits company fundamentals and relies on recent data; meeting the conditions does not imply future gains, and volatile candidates carry risk. It suggests adding financial measures such as return on equity and profit growth, and using a longer data window. The accompanying formula and Python example are references, but the Python range condition appears inconsistent with the stated threshold, so the implementation should be checked before use.

Key ideas

• The screen combines a minimum price range with a bounded volume ratio.
• It adds filters based on circulating market value and total shares.
• The author says recent price and volume conditions do not establish future performance.
• The post recommends incorporating fundamentals and considering a longer history.
• The accompanying Python range comparison appears inconsistent with the stated screen.
